The polls have opened for the Missouri 2012 Republican primary, but only three candidates will participate: Mitt Romney, Ron Paul and Rick Santorum.
As a result, Newt Gingrich has announced his conscious decision not to participate, and news sources have dubbed it a meaningless primary more akin to a beauty contest than a legitimate race.
Nonetheless, Missouri voters are still expected to show up, and certainly they will see which candidates are still courting their votes. And Rick Santorum, a no-show in the polls since the Iowa caucus, may be able to secure his first official win by playing the game.
Last-minute polls have the former Pennsylvania senator leading the pack with 45 percent of voters' support, Mitt Romney trailing Santorum at 32 percent, and Ron Paul at 19 percent. If Santorum wins the Missouri primary, his chances of winning its delegates at the March 17 caucus are greatly increased. Newt Gingrich's snub, meanwhile, could end up hurting him when the former speaker looks to court the Southern GOP vote.
